It's DRM restriction, not DRM protection. "Protection" sounds (intentionally so) like something good for the user, not something totally inimical to the user. As someone (RMS?) said, DRM manages rights like prisons manage freedom. It's all about device lock-in, and homie don't play that game.

Sigh, it only confuses the issue to try to change the term at this late date. Pretty much every one understands what DRM and copy protection mean...
